I fixed the affix stuff as much as possible (some of the structures are
re-palloc'd so they can't easily be included).  It appears that hacking
up regis, or any of the remaining allocations, wouldn't be worth the
trouble.  Using the Czech dictionary on a 32-bit machine, I see about
16MB going through the compacted-alloc code and only about 375K going
through regular small palloc's.
